Question
Ifthediameterofacapillaryisdoubled, then the rise of
water in it will be –Solution
Radius of a capillary tube is inverselyproportionaltotheheightoftheliquid column.So,if radiusofthetubeisdoubled, rise of level of water will becomes half of the previous rise in capillary tube. Capillary action, or capillarity, is the abilityof a liquid to flowin narrow spaces without the assistance of, and in opposition to external forces like gravity.
